Question

Suppose a student reaches in the bag and randomly selects nine red chips and eleven yellow chips. Based on this sample, what is a good estimate for the percentage of enrolled university students that are male?

Answer 1

the good estimate would be 9/20 and 11/20=20/20

Answer 2

A good estimate would be

`(9)/(20)` and
`(11)/(20)`.

Explanation:

To solve this problem, you can find the probability of each case, red chips and yellow chips, which are gonna be simple probabilities, that is, the quotient between the number of events and the number of possible outcomes.

We know that the student reaches nine red chips out of 20, the probability is

`P_(red)=(9)/(20)`

Also, the students reaches eleven yellow chips out of 20, so

`P_(yellow) =(11)/(20)`

Thefeore, a good estimate would be
`(9)/(20)` and
`(11)/(20)`.
